In his blog post on the topic, Olliver implies that it might be possible to try it with metals with higher melting points like aluminum or bronze, with proper research. Here is a photograph of the completed ring:

Also check out Thingiverse, which has plans for various designs for RepRap to fabricate. I really like the planetary gear calling card and Turner’s cube.

Plaster of Paris (which was used to shield the PLA from the …
